T 0 all whom it may concern:

Be. it known that I, WiL ELM E ADIUEs HANSON, of the town of Lajord, in the Province of Saskatchewan, Canada, have invented certain new andv useful Improve; ments in Barrel Hoists, of which thefollowing is the specification.

.The invention relates to. improvements. in barrel hoists and. an object oi the invention is to provide a device which will support a barrel or such like in. an inclined or pour-. ingposition and which canbe adjusted eitherv up or down through varying heights and without: having. to remove the. barrel Whilst the adjustment is being made, and further, to arrange the construction thereof such that the appliance automatically locks to support the barrel in any. adjusted position.

A further object of the invention is. to construct the appliance in a simple, cheap andv durable manner and so that the parts can be readily assembled.

A. further object of the invent-ion is, to construct the appliance so that the adjustment can be made up or downby thesimple expedient of rocking the. barrel or the rack provided for carrying the barrel.

Nith the above more important objects. in view the invention consists, essentially in the arrangement and construction of parts hereinafter more particularly. described and. later pointed out in, the appended claims, reference being had. to the. accompanying drawing in which: I

which is provi-ded with tw o upstanding sta V tion ary spaced; rack bars52 and 3, therack. bars having th opposite edgesf thereof 'fitt'ed:

p ingj s o.hbld thei51bwer nds h less riding the plate. Centrally, the plate is provided with notches 29, adapted to alternately catch the lower ends of the legs upon the cradle being rocked, as later more fully explained.

On account of the ratchet teeth of the rack bars being alternated it will be seen that the dogs will support the cradle in a normal inclined position. This is desirable as the contentsofthe barrel will run out freely by gravity, if provided'at the bottom with a tap 30 or such like. ment'of the dogs and associated'parts is such that the barrel can be raised or lowered as wished by rocking or oscillating the bar-' rel with the cradle. This action is now described, assuming the parts initially in the position as best shown in Fig. 1.

Upon theupper or elevated or left hand end ofthe barrel being pressed down, the dogs 15 become anchored on the engaged teeth of the rack bars and support the weight of the barrel, whilst the dogs 14 escape upwardly over the teeth of the rack bars with which they are engaged and become caught in the next notches higher up. Care is exercised that the left hand end of the barrel, at this time, be not pressed down too far, but simply far enough to permit the right hand dogs to escape into the next notches higher up. Then upon the right hand end of the barrel, which is at this time elevated, being pressed down, the cradle will be rocked in the opposite direction. The dogs 14 will then remain caught and the dogs 15 will then escape into the next notches higher up, it being borne in mind also that the barrel be rocked an amount sufiicient to permit the dogs simply to catch in the notches higher up.

Accordingly by alternately rocking the ends of the barrel and through the barrel the ends of the cradle, the cradle willgradually move up rack tooth by rack tooth until it is brought to the position desired, where it will remain. This is convenient as one can raise the barrel to drain it into receptacle's of. varying heights, or he can raise it well up to load it say into a wagon.

Further, the rack and'consequently the barrel become'suspended-in all cases in an inclined position so that one can pour from either end of thebarrel if needs be.

In the limited, so to speak, rocking movement given the ba'rrel in the aforesaiddescription, the legs are simply moving idly V backwardly and forwardly on the plates but than the position shown in Fig. 1, such I would resultin the out swinging of the dogs donot; become caught in the. notches 29.

Referring now to Fig. 1 it'will be ob served that if .the right hand end of the barrel were pressed downwardly further 15, such being brought about by the'inclined faces of the engaged teeth of the rack-bars.

The arrangeing the do s This further outward movement of the-said dogs 15 results in the backpulling of the legs carried by those dogs, the back pulling being to such an amount that the lower ends of the legs are permitted to enter and catch in the notches 29. As soon as the said legs become caught in the notches the dogs 15 are locked, in which position they are shown in Figures 5 and 6. Upon the left hand end ;of the barrel being then swung downwardly the dogs 14 will anchor the barrel in respect to the racks and the locked dogs 15 will swing out,'clear of and downwardly past the then underlying rack teeth and will reach a position as'shown in Figures 7 and 8;

After they have reached this position and the left hand end of the barrel is swung downwardly further, the lower ends of the legs ofthe dogs, 14 act to trip the legs'of the dogs 15 so that they are freed from the notches. Immediately this occurs the dogs 15 swing in under'the action of the spring and becomecaught in the next lower rack tooth.

This being accomplished one can force the left hand end of the barrel still further down and at'this time the dogs 15 serve to anchor and support the barrel, whilst the dogs 14 are forced out to an extreme position and locked by the legs associated in the dogs 14 escaping into the next rack tooth lower down.

Accordingly by giving the barrel and through the barrel the cradle an increased dip or down push I can cause the dogs to climb down the racks. The mechanism accomplishing this is extremely simple and positive and the operator, by gauging the tilting movement of the barrel, can raise it or lower it as he desires and without havingto set any parts by hand or otherwise, the whole action being entirely automatic.

What I claim as my invention is:

1'. In a hoist, a pair 'ofopposed spaced upright stationary rack bars having similar rack teeth located'at the sides thereofya car- .rier interposed between the bars, pairs of dogs supporting thecarrier from the teeth of the rack bars, and acontrol mechanism associated with the dogs; and carrier causbars, dependent upon the amount of up, and down swing given the ends of the carrier.

2. In ahoist, a pair ofsimilar opposing spaced upright stationary rack'bars having the opposite edges thereof, a cradle interposed between the ratchet teeth formed on to climb ordes'cend the rack rack bars, pairs of spring pressed dogs pivotally attached to the sides, of the cradle and engaging the teeth of the rack bars and supporting the cradle from the rack bars, said dogs being designed to alternately climb the rack bars upon the cradle being rocked a predetermined amount, and a combination dog locking and trip mechanism associated with the dogs and cradle and adapted to alternately lock and release the dogs of the pairs and in so doing causing the dogs to descend the rack bars in an abnormal rocking of the cradle.

3. In a hoist, a pair of similar opposed spaced upright rack bars having ratchet teeth formed on the opposite sides thereof and with the ratchetteeth at the opposite sides of the pairs alternating in position, a cradle interposed between the rack bars, pairs of spring pressed dogs pivotally attached centrally to the sides of the cradle and adapted to engage and cooperate with said teeth in supporting the cradle at an inclination with respect to said bars, and a combination dog locking and trip mechanism associated with the dogs and actuated by the rocking of the cradle a predetermined amount and adapted upon the cradle being rocked a predetermined amount to alternately lock and release the dogs and effect the descent of the dogs in respect to the rack bars and the consequent lowering of the cradle.

4. In a hoist, a pair of similar opposed spaced upright rack bars having ratchet teeth formed on the opposite sides thereof and with the ratchet teeth at opposite sides of the bars alternating in position, a cradle interposed between the rack bars, a pair of dogs pivoted to each side of the cradle at a central point adapted to engage and cooperate with said teeth in supporting the cradle in an inclined position with respect to said bars, trip legs pivotally connected to the dogs and having their lower ends riding the upper edges of the cradle sides,

the legs against the cradle, and means or alternately locking and releasing the lower ends of the legs to alternately lock and release the dogs and efiect the descent of the dogs on the rack bars upon the cradle be-' ing abnormally rocked.

5. In a hoist, a air of similar opposed spaced upright rack bars having ratchet teeth formed on the opposite sides thereof and with the ratchet teeth at opposite sides of the bars alternating in position, a cradle interposed between the rack bars, pairs of dogs pivotally attached centrally to the sides of the cradle and engaging the teeth of the rack bars to support the cradle at an inclination with respect to said bars, pairs of trip legs pivotally secured to the pairs of dogs, one of the trip legs of each pair being slotted to receive the other leg of the pair, plates secured to the upper faces of the sides of the cradle, said plates being each provided with a central notch adapted to receive and alternately lock the lower ends of the legs, said pairs of legs being further designed to alternately release one another from the notches in the rocking movement of the cradle, springs connecting the upper ends of the legs and holding the lower ends thereof ridingthe plates and also pressing the pairs of dogs toward the rack bars.

6. The combination of a supporting structure, an oscillatory load carrier movable vertcially with respect thereto, and means for causing the load carrier to ascend or descend the supporting structure dependent upon the extent to which the load carrier is oscillated.
